PUMP-JACK.-

SPECIFICATTON forming part of Letters Patent No. 787,462, dated April 18, 1905. I

' Application filed August 6, 1904. Serial No. 219,701.

To all whom it may concern; 'Be'it known that I, PHTLIP A. MYERS. a citizen of the United'states, residing at Ashland,

1 ments'i-n Pump-JacksJ-of which the following use in'connection with an ordinary pump, ,s'uch "as-is usually operated 'by a windmill or by .hand'at will. In those portions of'the counin the county'of- AshlandandState of Ohio, have'inyented certainnew and useful Improveis a specification, reference being had therein to the accompanying drawings.

This invention relates to pumping-jacks, and has forits object to provide an attachment for try where such pumps -are.employed to provide a supply of water reliance is usually placed upon the windmill as a motor-to operunavailable. 20.

atethe pump; but extended periods of calm frequently occur, when this motive power is In such periods provision ismade for operating the pump from any suitablemotor', such'as a horse-power, gas-engine, or the like; and the particular object of the direction of the arrows.

my present invention is to provide a jack which shall be readily applied to any pump and firmly maintained in'relation thereto,

which will serve to transmit powers received from the motor by means of a belt to the pump mechanism, and which shall be-simple, inexpensive, and of high efiiciency.

To these ends my invention consists in" certain novel features, which Iwill now proceed to describe and will then particularly point out in the claims.

In the accompanyingdrawings, Figure 1 is a perspective view illustrating my improved jack applied to a pump. Fig.2 is a similar view, showing the jack detached. Fig. 3 is a side elevation of the jack applied to the pump. Fig. 4 isan enlarged plan section taken on'the line w :v of Fig. 3 and looking in Fig. 5i's a detail view of. the crank-arm detached. Fig.6 is an enlarged detail sectional viewshowing the connection between thetwo members of the pitman; and Fig. 7' is a detail plansection' similar toFig. 4, but on a reduced scale, show inga modification.

In thesaid drawings, 1 indicates a pump as a whole, comprising tlge usualstandard 2, 'proshown disconnected vided with the base 3, by means of which it is secured to'the. usual platform or supportd. 5 indicates the piston-rod or windmill-bar, and '6 the handle for manual operation, which is drawingsf These parts may be of anyv approved construction.

in the accompanying The jack comprises a standard 7 in the form of a hollow pillar open at one side, as clearly shown in Figs. 1 and2, and having abase 8,

which is also hollow and open at one side, said jack-standard and its base being of dimensions such that .they will readily pass around and partly inclose the standard and base of the pump, as clearly shown in Figsl and 3. The jack'is secured to the platform orsupport 4, upon which'the pump-standard is mounted independently of said pump-standard, preferably by means, of bolts 9e The jack-standard is provided at. its upper end with a bea ringsleeve 10, in which is mounted a shaft 11, provided with a gear-wheel 12. Said jackstandard is further provided with a bracket comprising an inclined plate 13, extending downward "and rearward from'the bearingsleeve 10, and a vertical plate of web 14, conmeeting the! body of the standard and, saidplate 13; This bracket supports a shaft 15 by means of a bearing sleeve 16, and said shaft 15 is provided with a pinion 17, which meshes with the gear 12. The shaft 15is further provided with a fast pulley 18 and loose :pulley 19, by means of which power may be .applied to rotate the shaft 15 from any suitable'motor, such'asa horse-power, gas-engine, or the like. The pinion 17 may be provided "with a protective cap 20 to prevent the same from becoming clogged by ice'or snow or any other cause. Theshaft 1.1 projects beyond the bearing-sleeve 10 at each end, the gear wheel'12 being m'ounted'on one .of said pro-f jecting ends," while the other projecting end has secured on it acrarik-zirm 21 (Shown in detailin Fig. 5.) The gear-wheel 12 and the crank-arm 21 arev each provided with a plurality-of apertures 22, arranged at difierent distances or stroke of the pump may be readily adjusted. To this end two pitmen are employed,

from the shaft 11, so that the throw v each designated as a whole by the referencenumeral 23 and eachprovided' at its lowei end with a crank-pin 24, which may be socured in any one of the apertures 22 of the gear-wheel 12 or crank-arm 21. The upper ends of the pitmen 23 are connected to the piston-rod or windmill-bar 5 in' any suitable manner, preferably by means of the same pin 25 ,which is employed to connect the pump handle 6, said pin being readily removable to permit the connection of the pump-handle or of the pitmen, as desired. The pitmen 23 thus lie upon opposite sides of the pump when the jack is in place and operate upon the same with a practically vertical movement. Since pumps vary considerably in their dimensions and structure, it is necessary not only to regulate the stroke of the pitmen 23, but also to regulate the distance between the crank-pins 24: and the point of connection of the uppercnds of said pitmen at 25. To this end the pitmen are each made in two parts, the one member, preferably the lower part, (indicated by the reference-numeral 26,) being in the form of a hollow sleeve internally threaded, into which is screwed" the' lower end of the other member, 27, which is correspondingly threaded at its lower portion. By screwing the member 27 further in the member 26. the pitman may be shortened, while a reversal of this operation will lengthenthe pitman. A lock-nut 28, mounted on the member 27, may

. be screwed up against the end of the member a tion with which 26 to hold the parts firmly in the position to which they be adjusted. The jack thus organized may be readily applied to any'commercial pump of the general class in connecit is to be used, and this application is effected by placing the jack upon the same platform or support that the pump is mounted on, moving it up to the pump until. it partially surrounds and incloses the same, as shown more particularly in Fig. 1 of the drawings.

with the pump-standard, so as to have a firm bearing against the same. The jack-standard is then secured to the platform or support, this being accomplished entirely independ- -"-'ent l y of the pump, with which the jack-standof, gives a firm and extensive support for the jack, which support is supplemented when necessary .by the bearing of thef'sleeve 10 against the pump. This construction brings the shaft 10 so close to the central vertical line of the pump that the working strains on Preferably the jack is moved up to the pump until the bearing-sleeve 10 at the top of the jack-standard comes into contact the jack-standard, practically sur-' rounding the pump-base on three sides therel the pitmen and pump-rod are practically'in line with the travel of this latter part. It will be seen, therefore, that the jack can be readily and quickly set up and fastened ,in

position without connecting in any way with the pump, thus requiring no special construction for this latter purpose and increasing 1 the range of pumps to which the device is.

applicable, while the proper alinement of the ljack relative to the pump may be readily effected.

Modifications of the structural details will readily suggest themselves to those skilled in the art, and' I therefore do not wish to be understood as limiting myself to the precise details of construction hcreinbefore described, and shown in the accompanying drawings. For instance, although it is not necessary, as 1 have already stated, to connect the jacl standard to the pump-standard it may be found desirable to do so on certain occasions,

in which case such connection may be readily effected, as shown in Fig. 7, by the employment of a clip or U-bolt 29, the bend of which may embrace the pump-standard 2, while'its threaded ends pass loosely through lugs 30 on the sleeve 10 and are provided back of said lugs with nuts 31, which bear against the lugs and clamp the pump-standard and jack-standard firmly'togethcr. Furthermore, the train of gearing between the cranlcshaft and pulley-shaft may be obviously modified as occasion may require.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A pumping-jack comprising a hollow standard and base open at one side to receive the pump standard and. base, and adapted for independent connection to the platform or support on which the pump is mounted and gearing mounted on said standard and adapted for connection with the pump-rod to convert the rotatory motion of said gearing to a recip tially as described.

2. A pumpingjack comprising a hollow standard and base, open at one side to receive the pump standard independent connection to the platform or su p port on which the pump is mounted, said jackstandard being provided with a bearing-sleeve at the top thereof adapted to bear against the pump-standard, acrank-shaft mounted in said bearing-sleeve,and pitmen connected with said crank-shaft and adapted to be connected to the pump-rod, substantially as described.
